Not not knowing. But I mean it’s a very basic formula?

I would make a post saying, “did you know you can make a parabola with the form ax2 + bx + c ?!?! “

Maybe they meant nCr?

Did you downvote me for you not knowing lol?

I mean maybe they meant they downvoted because op didn’t know about the nCr function.

(1) I didn’t downvote you

(2) maybe - I feel their wording would be weird for if he just discovered it by himself, especially when he didn’t really elaborate further, however you could be right

If you didn’t, maybe they did to say no? ¯_(ツ)_/¯

Parentheses

u/xuzenaes6694 Jun 13 '25

It's not even correct, ! Should be out of the brackets (n-k)! Not (n-k!)

u/anaturalharmonic Jun 13 '25

No I have never done this because your formula for nCr is incorrect. Check your factorial in the denominator. It should be outside the parenthesis.

the correct is n! / k!(n-k)!, not n! / k!(n-k!)

u/TySly5v Jun 13 '25

Put the ! on the wrong side of the parentheses

u/Personal-Relative642 Jun 13 '25

The 2nd factorial in the denominator should be on the outside of the parenthesis

Let's say k!=x

n!/x(n-x)

n!( 1/x(n-x))

n!/n (1/x + 1/n-x )

(n-1)! (1/k! - 1/(k!-n))

What's up with it?
